Atmospheric auxiliary data used in the processing of Landsat Collection 2 Level-2 products are available for download to enable users to generate their own Level-2 surface reflectance and surface temperature products from Collection 2 Level-1 calibrated data using custom algorithms.

USGS Landsat Collection 2 Level-2 surface reflectance and surface temperature data processing requires atmospheric auxiliary data from multiple external sources. The required external data is extracted from the original source data and the parameters specific to generating a Collection 2 Level-2 product are then repackaged and made available for download.
NOTE: Collection 2 Level-2 surface reflectance and surface temperature standard products are easily downloadable from EarthExplorer; it is not necessary for users to download the atmospheric auxiliary data to use Level-2 products.
Please visit the Landsat Collection 2 Atmospheric Auxiliary Data for more information, and contact USGS Customer Services with any questions: custserv@usgs.gov.
Landsat Collection 2, the second major reprocessing effort on the Landsat archive, resulted in several data product improvements that applied advancements in data processing, algorithm development, and data access and distribution capabilities.
Landsat Collection 2 contains Level-1 data from Landsat 1-9, and science products from Landsats 4-9.
